Description

IMAGE CAPTURING APPARATUS AND CONTROL METHOD THEREOF}

The present invention relates to an imaging device and a control method thereof.

An imaging device such as a digital camera or a digital video camera is provided with various operation devices (buttons, switches, etc.). However, with the downsizing of the imaging device, the installation space for accommodating the operation devices is insufficient. Although the operating device can be miniaturized in accordance with the size of the installation space, there is a limit to how small the operating device can be.

For this reason, Japanese Patent Laid-Open No. 2000-125184 proposes an imaging device that receives an input instruction without using an operation device by using a vibration sensor provided for camera vibration detection.

The technique described in Japanese Patent Laid-Open No. 2000-125184 makes it possible to input an instruction which can also be input by the operation device even by vibrating the imaging device. And even while the vibration is detected, the input from the operation device is received.

Therefore, when the user vibrates the imaging device in order to input a desired instruction, and inadvertently operates an operation device such as a menu button, there is a problem that an unintended instruction could be detected by the imaging device.

(Technical Challenges)

However, the technique described in Japanese Patent Laid-Open No. 2000-125184 allows input of instructions that can also be input by the operation device even by vibrating the imaging device. And even while the vibration is detected, the input from the operation device is received.

Therefore, when the user vibrates the imaging device in order to input a desired instruction, and inadvertently operates an operation device such as a menu button, there is a problem that an unintended instruction could be detected by the imaging device.

The present invention has been devised in view of the problems of the background art as described above, and is unintentional when the imaging device is vibrated to input a desired instruction, and an operation device such as a menu button is accidentally operated. An imaging apparatus or method is provided that prevents instructions from being input to an imaging apparatus.

(Solution of task)

(First Embodiment)

1 is a block diagram showing a functional configuration example of a digital still camera (hereinafter, simply referred to as a camera) as an example of the imaging device according to the first embodiment of the present invention.

Light incident from a subject is imaged as a subject image by the optical system 1001 consisting of a lens and an aperture on an imaging surface of an imaging device 1003 which is a photoelectric conversion element such as a CCD image sensor or a CMOS image sensor. The mechanical shutter 1002 opens and blocks the optical path from the optical system 1001 to the image pickup device 1003 under the control of the drive control unit 1007.

The CDS circuit 1004 is a correlated double sampling circuit, and performs analog signal processing such as correlated double sampling on an analog image signal output from the imaging device 1003. The A / D converter (A / D) 1005 converts the analog signal output from the CDS circuit 1004 into a digital signal. The timing signal generator 1006 generates a signal for operating the drive control unit 1007, the imaging device 1003, the CDS circuit 1004, and the A / D converter 1005.

The drive controller 1007 drives the aperture and autofocus mechanism of the optical system 1001, the mechanical shutter 1002, and the imaging device 1003 in response to the signal from the timing signal generator 1006.

The signal processing unit 1008 performs signal processing on digital image data output from the A / D converter 1005 to generate image data for display and recording, such as color interpolation processing and white balance processing. The image memory 1009 stores image data processed by the signal processing unit 1008. The recording control unit 1011 records image data output by the signal processing unit on a removable recording medium 1010 detachable from a camera such as a memory card. The recording control unit 1011 further reads the image data recorded on the recording medium 1010.

The display control unit 1013 generates a display image signal from the image data output from the signal processing unit 1008 and displays the image signal on the image display unit 1012. The system control unit 1014 controls the entire camera.

The nonvolatile memory (ROM) 1015 includes a program describing control performed by the system control unit 1014, control data such as parameters and tables used when executing the program, and a defective pixel address of the imaging device 1003. Store correction data. When the system control unit 1014 operates, the program, the control data and the correction data stored in the ROM 1015 are transferred to the RAM 1016.

The operation unit 1017 includes an operation device for allowing a user to input instructions to the camera, such as a button, a switch, a touch panel, and the like. In addition, the operation unit 1017 includes a mode switch and can selectively set individual function modes such as a power off mode, an imaging mode, a reproduction mode, and a PC connection mode.

The vibration detection sensor 1018 is an acceleration sensor in this embodiment, and detects the vibration applied to the camera. The vibration determination unit 1019 determines the validity of the instruction input from the operation unit 1017 based on the output of the vibration detection sensor 1018. The signal output unit 1020 detects the vibration of the camera based on the output of the vibration detection sensor 1018, and recognizes the instruction input by the user by vibrating the camera from the detected vibration information. In the present embodiment, although the instruction is recognized in accordance with the detected direction of vibration, other information about the vibration such as the magnitude and the number of vibrations may be considered. And based on a recognition result, the signal output part 1020 outputs the signal to the system control part 1014 which means the some instruction | indication which can operate and input the operation device contained in the operation part 1017. FIG.

The signal output unit 1020 has a table, not shown, which correlates, for example, information about vibrations such as the direction and number of vibrations with corresponding instructions. The signal output unit 1020 recognizes the instruction by referring to the table according to the information about the vibration detected based on the output of the vibration detection sensor 1018. In the present embodiment, the signal output by the signal output unit 1020 to the system control unit 1014 is the same as the signal output to the system control unit 1014 when any one of the operation devices of the operation unit 1017 is operated. . That is, in the camera of this embodiment, at least part of the instructions that can be input using the operation unit 1017 can be input even by vibrating the camera in a specific direction.

The person / landscape position detection sensor 1021 provided as needed detects whether a camera is a landscape position or a person position, and outputs the detection result to the system control part 1014. FIG. At this time, the vibration of the camera may be detected using the person / landscape position detection sensor 1021. In this case, the vibration detection sensor 1018 is unnecessary.

Next, an image capturing operation (general still image capturing operation) using the mechanical shutter 1002 in the camera having the above-described configuration will be described.

Prior to the imaging operation, at the start of the operation of the system control unit 1014 (such as when the camera is powered on), the system control unit 1014 stores the necessary programs, control data, and correction data from the ROM 10015 in the RAM 1016. Remember to send to. In addition, the system control unit 1014 may transfer additional programs and control data from the ROM 1015 to the RAM 1016 as needed, or may read or use the data in the ROM 1015 directly.

2A is a rear view showing an appearance example of a camera according to an embodiment of the present invention.

In the example shown in FIG. 2A, a release button 2001 and a zoom lever 2002 for changing the focal length of the zoom lens of the optical system 1001 are provided on the upper surface of the camera. In addition, the rear of the camera is provided with a mode dial 2003 for changing the imaging mode, and a function button 2004 for performing various settings, including a direction cursor and a decision key. On the back side, a menu button 2005 for displaying various setting menus on the image display unit 1012 and a display button 2006 for switching the display of the image display unit 1012 are further provided. These buttons, dials, and keys are all included in the operation unit 1017.

The release button 2001 has a structure in which the first switch is turned ON when pressed halfway and the second switch is turned on when pressed to the end. When the first switch is turned on, the system control unit 1014 starts an imaging preparation operation including AE processing and AF processing. The system control unit 1014 then drives the aperture and lens of the optical system 1001 via the drive control unit 1007 to form an image of a subject having an appropriate brightness on the imaging device 1003. Then, when the second switch is turned on, the system control unit 1014 starts an imaging operation (i.e., an imaging operation for recording), and then exposes the mechanical shutter 1002 to the appropriate exposure based on the AE process via the driving control unit 1007. By opening in time, the imaging device 1003 is exposed. At this time, when the imaging device 1003 has an electronic shutter function, it may be used in combination with the mechanical shutter 1002 to secure a necessary exposure time.

The imaging device 1003 is driven by a drive pulse generated from an operation pulse generated by the timing signal generator 1006 controlled by the system control unit 1014, and converts the image of the formed image into an electrical signal by photoelectric conversion. And output as an analog image signal. The analog image signal output from the image pickup device 1003 is removed from the clock synchronism noise by the CDS circuit 1004 operating with an operation pulse generated by the timing signal generator 1006, and the analog image signal is then A / D. The converter 1005 converts the digital image signal.

Next, in the signal processing unit 1008 controlled by the system control unit 1014, the image processing such as color conversion, white balance, gamma correction, and resolution for the digital image signal output by the A / D converter 1005 is performed. Conversion processing, image compression processing, and the like are performed to generate image data.

The image memory 1009 is used by the signal processing unit 1008 to temporarily store a digital image signal being processed, or to store image data which is a signal processed digital image signal. The image data generated by the signal processing unit 1008 is converted into data (for example, file system data having a hierarchical structure) suitable for the recording medium 1010 in the recording control unit 1011, and stored in the recording medium 1010. Is recorded. The image data is converted into a signal (for example, an NTSC analog signal) suitable for the image display unit 1012 in the display control unit 1013 after resolution conversion in the signal processing unit 1008, thereby converting the image display unit ( 1012).

In this regard, the signal processing unit 1008 does not perform image processing on the digital image signal in accordance with the control signal from the system control unit 1014, and outputs the image data to the image memory 1009 or the recording control unit 1011 as it is. You may also In addition, the signal processing unit 1008, when requested by the system control unit 1014, outputs the information of the digital image signal and the image data generated during the processing of the signal processing, or information extracted from such information, to the system control unit 1014. Output to. Such information includes, for example, the spatial frequency of the image, the average pixel value in the designated area, the data amount of the compressed image, and the like. Furthermore, in response to a request from the system control unit 1014, the recording control unit 1011 outputs information such as the type and the free capacity of the recording medium 1010 to the system control unit 1014.

When the image data recorded on the recording medium 1010 is reproduced, the recording control unit 1011 reads out the image data to be reproduced from the recording medium 1010 by a control signal from the system control unit 1014. Then, in response to the control signal from the system control unit 1014, the signal processing unit 1008 performs decompression processing of the image data and stores it in the image memory 1009 when the image data is a compressed image. The image data stored in the image memory 1009 is converted into a display resolution suitable for the resolution of the image display unit 1012 by the signal processing unit 1008 and then converted into a signal suitable for the image display unit 1012 in the display control unit 1013. The image is converted and displayed on the image display unit 1012.

Next, the vibration determining unit 1019 will be described.

In the present embodiment, the vibration detection sensor 1018 is, for example, an acceleration sensor, detects an acceleration component of vibration applied to the camera, and detects the vibration operation of the camera. This vibration detection sensor 1018 independently of the camera acceleration in three directions of the X-axis direction, Y-axis direction, Z-axis direction in the coordinate system (hereinafter referred to as camera coordinate system) shown in Fig. 2B It is possible to detect. The posture of the camera shown in FIG. 2B is called a home position. In this case, for example, in the camera coordinate system, the Y axis is in the opposite direction to which gravity is applied, the Z axis is parallel to the optical axis of the optical system 1001, and the X axis is orthogonal to the Y axis and the Z axis. It can be defined as a coordinate system facing in (i.e., horizontal direction).

At this time, if the vibration in one or more specific directions can be detected, there is no restriction | limiting in particular in the kind, number, and arrangement | positioning of a sensor. For example, an angular velocity sensor or a gravity sensor can also be used instead of the acceleration sensor. At this time, when the camera has a sensor for camera vibration detection and the person / landscape position detection sensor 1021, you may use them as a vibration detection sensor in a present Example. In FIG. 2B, the origin of the camera coordinate system is illustrated as coinciding with one vertex when the housing of the camera is regarded as a rectangular parallelepiped, but the position of the origin is not particularly limited.

<Acceleration Detection Waveform in Waving / Vibration Operation>

The output signal indicating the acceleration in the direction of each axis obtained by the vibration detection sensor 1018 is input to the vibration determining unit 1019. 4A to 4C and 5A show examples of signals input from the vibration detection sensor 1018 to the vibration determining unit 1019.

4A to 4C are signal waveforms showing the time change of the X-axis component of the acceleration detected by the vibration detection sensor 1018 when the camera is shaken up or shaken down. The horizontal axis represents time, and the vertical axis represents the acceleration component detected when the camera is shaken up from the horizontal position.

Fig. 4A is a signal waveform showing the time change of the acceleration component in the X-axis direction when the camera is accelerated at the start of shaking up from the horizontal state and decelerated and stopped at the timing of shaking up. FIG. 4A corresponds to a state transitioned from the state 40 of FIG. 3A to the state 41, and the acceleration is detected at the acceleration time of the start of shaking (peak 501) and the deceleration time of the shaking end (peak 502). Since the camera coordinate system shifts from the state of FIG. 3B to the state of FIG. 3C, the X-axis component of the gravitational acceleration in the stationary state before and after shaking is as shown in FIG. 3C from the Og level as in FIG. 3C. It changes to g level.

Fig. 4B shows the X-axis component of the acceleration detected by the vibration detection sensor 1018 when it is decelerated and stopped when it is accelerated and shaken down from the state of shaking the camera upward and then shaken downward in the horizontal position. Signal waveform indicating time change. That is, FIG. 4B corresponds to the state which shifted from the state 41 of FIG. 3A to the state 40, and acceleration is detected at the acceleration time of the shaking start (peak 503) and the deceleration time of the shaking end (peak 504). Since the camera coordinate system shifts from the state of FIG. 3C to the state of FIG. 3B, the X-axis component of the gravitational acceleration in the stationary state before and after shaking is Og as shown in FIG. 3C as shown in FIG. 3B. The level is changed.

Fig. 4C shows a signal waveform showing the time change of the X-axis component of the acceleration detected by the vibration detection sensor 1018 when the camera is shaken up and then shaken down. As can be seen from the comparison between Figs. 4A to 4C, the signal waveform of Fig. 4C is almost the sum of the signal waveforms shown in Figs. 4A and 4B. The peak 505 in FIG. 4C is the peak of acceleration that appears when the shake up operation is performed. Peak 506 is the peak of the acceleration that appears when the deceleration at the up wave and the acceleration at the down wave are completed when going to enter the down wave after the up wave is finished. The peak 507 is a peak of acceleration which appears at the time of deceleration at the end of the shaking operation. The peak 505 representing the acceleration at the start of shaking up is the first acceleration waveform, the peak 506 representing the synthesis of the acceleration at the end of shaking up and the beginning of the shaking down, and the acceleration at the end of the shaking down. The peak 507 shown is defined as a third acceleration waveform.

Among these, the peak 506 defined as the second acceleration waveform tends to be as large as the gravitational acceleration, and thus can be effectively used when detecting the camera shake motion based on the acceleration. FIG. 4C shows the signal waveform of the acceleration detected in the case of an operation that once shakes the camera up and then shakes down, but in the case of an operation that shakes the camera up once after shaking the camera down, It becomes a waveform.

Fig. 5A shows the signal waveform of the X-axis component of the acceleration detected by the vibration detection sensor 1018 (acceleration sensor in this embodiment) when the camera is shaken up and then shaken down as shown in Fig. 4C. An example is shown. The horizontal axis represents time, and the vertical axis represents the output of the vibration detection sensor 1018, with each symbol representing the direction of acceleration.

Threshold A and threshold value -A which are 1st threshold values are used to determine whether the camera of a present Example is moving. Specifically, the vibration determining unit 1019 determines that the camera is not moving when the absolute value of the acceleration detected by the vibration detection sensor 1018 is within the threshold A or less, and the absolute value of the acceleration is determined by the first value. If it is above the threshold, it is determined that the camera is moving.

Further, the threshold B and the threshold -B, which are the second thresholds, are used to determine whether the camera is shaken with a predetermined shake characteristic. Thresholds A, -A, B, and B are set to satisfy the relationship between threshold -B < threshold -A and threshold A < If the absolute value of the acceleration detected by the vibration detection sensor 1018 is greater than or equal to the threshold A and less than the threshold B, the vibration determining unit 1019 determines that the camera is moving but does not shake with the predetermined shaking characteristic. On the other hand, when the absolute value of the acceleration detected by the vibration detection sensor 1018 is equal to or greater than the threshold value B, the vibration determining unit 1019 determines that the camera is moving and shakes with a predetermined shake characteristic.

In addition, the threshold value C and the threshold value -C which are 3rd threshold values are used to determine whether the camera was shaken within the range of predetermined intensity | strength. The thresholds B, -B, C, and -C are set so as to satisfy the relationship of threshold value -C < threshold value -B and threshold value B < If the absolute value of the acceleration detected by the vibration detection sensor 1018 is greater than or equal to the threshold value B and less than or equal to the threshold value C, the vibration determining unit 1019 determines that the camera is shaken within a predetermined intensity range with a predetermined shaking characteristic. . On the other hand, if the absolute value of the acceleration detected by the vibration detection sensor 1018 is equal to or greater than the threshold C, the vibration determining unit 1019 determines that the camera is shaken too strongly. If the camera is shaken strongly, there is a high possibility of falling out of the user by mistake. Therefore, the camera warns if it is determined that the camera shakes too strongly. As a warning method, a warning sentence may be displayed on the image display unit 1012, or a loudspeaker warning sound may be generated.

The vibration determination unit 1019 may compare the acceleration with the threshold value of the government unit without comparing the acceleration value detected by the vibration detection sensor 1018 with a threshold value having the same absolute value as the absolute value. For example, it is assumed that the vibration determining unit 1019 compares the detected acceleration with the first threshold value. If the detected acceleration is greater than -A and less than + A, the vibration determining unit 1019 determines that the camera does not move (shake). On the other hand, the vibration determining unit 1019 determines that the camera is moving when the detected acceleration is below -A or above + A. The same applies to the remaining threshold values.

Among the peaks 301 to 303 in the signal waveform of FIG. 5A, the target operation is more likely to shake more strongly than the preparation operation. Therefore, the peak acceleration 302 having the largest absolute value of acceleration is the second acceleration waveform shown in FIG. 4C. Corresponds to That is, the signal waveform means shaking down when the camera shakes down, and shaking up when the camera shakes up. In this case, the peak 301 is the first acceleration waveform shown in Fig. 4C, and indicates the acceleration of the up-shake operation which is the shake-down preparation operation if the target motion is the shake-down operation. In addition, the peak 303 is the third acceleration waveform shown in Fig. 4C, and shows the waveform obtained when the deceleration at the time of shaking downward is detected. If the intended motion is a rocking motion, the waveform is symmetrical in both directions with respect to the X axis (the sign is opposite to the X axis), so that the first acceleration waveform 301 and the third Acceleration waveform 303 shows a shake up. At this time, the waveform with the largest absolute value of acceleration does not necessarily represent the intended operation. The detection method of the target operation | movement in this invention is demonstrated later.

Reference numeral 310 denotes a time point when the first acceleration waveform 301 crosses the threshold A (or -A). Reference numeral 311 denotes a time point when the second acceleration waveform 302 crosses the threshold A (or -A) for the first time, and reference numeral 313 indicates that the second acceleration waveform 302 crosses the threshold A (or -A) again. Represents a time point. Reference numeral 314 denotes a time point where the third acceleration waveform 303 crosses again after the threshold A (or -A) has been exceeded once. The threshold value S1 and the threshold value S2 are threshold values at the time duration time t1 in which the second acceleration waveform representing the target operation (the present operation) is continuously above the threshold A or below the threshold -A. . That is, the duration time t1 is until the second acceleration waveform 302 becomes equal to or greater than the threshold value A, and then reaches the threshold value A (or becomes equal to or lower than the threshold value -A and then becomes the threshold value -A). It's time. In the present embodiment, the vibration determining unit 1019 determines that the second acceleration waveform (this operation) has been detected when the condition of the threshold value Sl ≤ duration time t1 ≤ threshold value S2 is satisfied.

In addition, the vibration determining unit 1019 stops the shake operation of the camera when the state (the acceleration is greater than the threshold value -A and less than the threshold value A) for which the camera is not moving elapses for more than the time period of the threshold value E. Determine that it is in one location. In this case, the vibration determining unit 1019, if the state is determined that the camera is not moving for a time shorter than the threshold value E continues, at the time when the acceleration is at least the threshold value A or below the threshold value -A It is determined that the operation started is continued (one shake operation is performed).

Therefore, the vibration determination unit 1019 determines, for example, the third acceleration waveform 303 of FIG. 5A as a series of operations with the first acceleration waveform 301 and the second acceleration waveform 302. When the acceleration is greater than the threshold value -A from the time point 314 and the state below the threshold value A has elapsed more than the time of the threshold value E, and the acceleration becomes less than the threshold value -A or more than the threshold value A, the vibration determination unit ( 1019 determines that a new operation has been initiated.

In FIG. 5A, three threshold values A, B, and C having the same absolute value are used as the threshold value of the acceleration level, but one or more of the absolute value of the positive threshold value and the negative threshold value may be different.

FIG. 5B is a diagram showing the time change of the acceleration signal change rate when removing the offset component from the acceleration output signal of FIG. 5A. The acceleration signal change rate may be used as the threshold value used to determine whether the camera described with reference to FIG. 5A is moving or not. In this case, THh and THl are used instead of the threshold value ± A in FIG. 5A. In addition, THh and THl may be used instead of ± B or ± C in FIG. 5A, and the threshold value of the acceleration signal change rate may be separately determined.

The vibration determining unit 1019 determines whether or not the camera is vibrating along the axial direction based on the acceleration signal output in the given axial direction or the rate of change of the acceleration signal as shown in Fig. 5A or 5B. The determination result is output to the control unit 1014. The system control unit 1014 validates or invalidates the operation of the camera by the operation device included in the operation unit 1017 based on the determination result.

<User Operation Recognition Processing>

6 is a flowchart for explaining the outline of the user operation recognition processing during the imaging waiting of the camera according to the present embodiment.

First, the vibration determination unit 1019 determines whether the camera is vibrating in the X-axis direction from the acceleration output signal in the X-axis direction of the vibration detection sensor 1018 (S8001). The vibration determining unit 1019 determines whether the camera is vibrating in the X-axis direction using, for example, the magnitude, direction, and frequency of the peak of the acceleration signal output or the acceleration signal change rate in the X-axis direction. do.

Specifically, as an example, the vibration determining unit 1019, the camera is the X-axis whenever a state that satisfies the following two conditions continues for a certain period or a predetermined number of consecutive peaks satisfy those two conditions Determine that we are vibrating in the direction:

(1) the period in which the peak of the acceleration signal output or the acceleration signal change rate in the X-axis direction deviates from a predetermined threshold range (A to -A if the acceleration signal output is high and THh to THl if the acceleration signal change rate is lower than the predetermined period); And

(2) consecutive peaks are reversed.

As another example, the vibration determining unit 1019,

(a) It is determined that vibration is detected when the rate of change of the acceleration signal in the X-axis direction is out of a predetermined threshold range (for example, the threshold value ± A in FIG. 5A),

(b) After it is determined that vibration is detected in (a), the state where the output of the acceleration signal change in the X-axis direction is within the predetermined threshold range is longer than the predetermined time (for example, the threshold value E in Fig. 5A). If it continues, it is determined that the shaking operation is stopped.

During the period from the state defined by (a) to the state defined by (b), for example, the rate of change of the acceleration signal in the X-axis direction is within a predetermined threshold range (for example, the range of the threshold value ± A in FIG. 5A). Even in the case of M), it is determined that the operation is in progress.

On the other hand, when these conditions are not satisfied, the vibration determining unit 1019 determines that the camera does not vibrate in the X-axis direction. The vibration determining unit 1019 can similarly determine the Y axis direction and the Z axis direction. At this time, the said vibration determination method is a simple example, You may determine the presence or absence of vibration using another method.

When it is determined that the camera is not vibrating in the X axis direction, the vibration determining unit 1019 determines whether the camera is vibrating in the Y axis direction from the acceleration output signal in the X axis direction of the vibration detection sensor 1018. It determines (S8002).

When the vibration determining unit 1019 determines that the camera does not vibrate at all in the Y-axis direction, does the camera vibrate in the Z-axis direction from the acceleration output signal in the Z-axis direction of the vibration detection sensor 1018? It is determined whether or not it is (S8003).

The vibration determination unit 1019 outputs the determination result to the system control unit 1014 along each axial direction. The system control unit 1014 then invalidates the camera operation by the operation unit 1017 when the system controller 1014 obtains the determination result of which one is vibrating in the axial direction (S8005). When the operation by the operation unit 1017 is invalidated, the system control unit 1014 ignores the input from the operation unit 1017. In this way, even when the user (for example) attempts to input a desired instruction by vibrating the camera, the operation unit (even when the menu button 2005, the mode dial 2003, etc. of the operation unit 1017 is mistakenly operated). Unintended input by 1017) can be prevented.

However, in the present embodiment, the operation of the release button 2001, especially the on of the second switch, does not ignore the system control unit 1014 even when the operation by the operation unit 1017 is invalid. Whether the operation by the operation unit 1017 is valid or invalid can be stored, for example, as a flag in the RAM 1016.

At this time, although not specifically described in the flowchart of FIG. 6, when the vibration in a specific axial direction is recognized as a command or an input of an instruction, the system control unit 1014 is based on the detection result output by the vibration determination unit 1019. On the basis of this, recognition processing is performed. The system control unit 1014 then performs an operation in accordance with the recognized command or instruction.

The vibration determining unit 1019 may output the determination result for each determination along each axis, or may output the combined judgments for all the axes. In addition, the vibration determining unit 1019 may output the judgment result only along the axis or axes determined to be vibrating (that is, if no axis is determined to be vibrating, the judgment result is not output). Alternatively, when it is determined that the vibration determination unit 1019 vibrates along a certain axis, the vibration determination unit 10 may omit the determination processing on the remaining axes (except cases where the specific combination of vibration directions is set to be recognized as the instruction input). ).

If it is determined that the camera is not vibrating along either axis, the system control unit 1014 validates the camera operation by the operation unit 1017 (S8004). At this time, normally, the operation part 1017 is effective. Therefore, if the operation of the operation unit 1017 is not invalidated, the system control unit 1014 does not need to specifically perform a process for validating the operation in S8004.

The system control unit 1014 determines whether an instruction to start imaging is input, that is, whether or not the second switch of the release button 2001 is on (S8006). If the second switch is off, the process from S8001 is repeated. When the second switch is on, even when the camera operation by the operation unit 1017 is invalid, the system control unit 1014 performs the imaging process (S8007).

That is, in the camera of this embodiment, when the on of the second switch of the release button 2001 is detected, imaging is performed. This is because the complete stroke operation of the release button 2001 in which the second switch is turned on is likely to be an intentional operation instead of an incorrect operation. On the other hand, the on of the first switch by the half stroke operation of the release button 2001 is ignored when the operation unit 1017 is invalid. However, while the first switch is kept on, vibration along any of the axes of the X, Y, and Z axes of the camera is no longer detected, and the operation of the camera by the operation unit 1017 is effective. When released, the ON of the first switch is also effective. In response to the on of the first switch, the system control unit 1014 starts an imaging preparation operation called AE processing and AF processing.

As described above, according to the present invention, in a camera capable of inputting an instruction and a command by vibrating the apparatus, an instruction not intended by the user by an unintended button or key operation when the apparatus is vibrated. The input of can be suppressed.

(Second Embodiment)

The present embodiment is characterized by enabling the user to instruct forward and backward transfer of an image reproduced by the portable device by shaking the portable device (at least a camera capable of setting at least one of the playback mode and the imaging mode). . The user can view an image recorded on the recording medium 1010 through the image display unit 1012 or the like by setting the portable device to the reproduction mode. At this time, as an example of the portable device according to the present embodiment, the camera described in the first embodiment is used. Therefore, the description of the hardware configuration, the shaking motion detection method, and the like will be omitted. Also in this embodiment, the determination related to the shaking motion of the camera is performed by detecting the acceleration in the X-axis direction.

7 is a flowchart for explaining processing relating to one shake operation. First, the system control unit 1014 determines whether the camera is set to the reproduction mode (S700). If the playback mode is set, the system control unit 1014 executes the processing after step S701. When the acceleration detected by the vibration detection sensor 1018 exceeds the threshold value A or the threshold value -A shown in FIG. 5A (time point 310 in FIG. 5A), the vibration determination unit 1019 detects that the camera has moved (S701). ). When the vibration determining unit 1019 detects that the camera has moved (shakes), the system control unit 1014 invalidates the operation of the camera by the operation unit 1017 (S702).

The acceleration is detected in the detection period of the predetermined vibration detection sensor 1018. In addition, the vibration determination unit 1019 stores the detection value obtained by the vibration detection sensor 1018, and transfers the detection value obtained at every detection period after the detection value is lower than the threshold value -A at the time point 310. Each time the peak value (minimum value) is updated, the stored peak value (minimum value) is updated. Therefore, the vibration determination unit 1019 can measure the peak value (minimum value) of the detection value after the detection value is less than the threshold value -A. The vibration determining unit 1019 can also measure the peak value (maximum value) facing upwards in the same manner.

When it is detected in S701 that the camera has moved, and the process of detecting the motion is started in S702, the vibration determining unit 1019 first detects the first acceleration waveform. The vibration determination unit 1019 determines that the first acceleration waveform has been detected when the detected acceleration detected by the vibration detection sensor 1018 exceeds the threshold value A or -A after the camera is determined to have moved.

When the first acceleration waveform is detected, the vibration determining unit 1019 next performs a detection process for the second acceleration waveform. The vibration determination unit 1019 detects the start of the second acceleration waveform when the detection acceleration exceeds the threshold value A (or threshold value -A) (time 311). When the detection acceleration exceeds the threshold value A (or threshold value -A) again at the time t1 of satisfying the condition of the threshold value Sl ≤ duration time t1 ≤ threshold value S2 (time 313), the vibration determining unit 1019 The end of the second acceleration waveform is detected. As described above, if the duration time t1 does not satisfy the above condition, the vibration determining unit 1019 does not determine that the second acceleration waveform is detected. Furthermore, from the time point 311 to the time point 313, if the detection acceleration exceeds the threshold B (or threshold -B) (point 312) and does not reach the threshold C (or threshold -C), the vibration determination unit 1019 ) Determines that the camera is shaken correctly (with a certain intensity) (Y es in S703).

In addition, the vibration determining unit 1019 determines whether the camera is shaken up or down based on the sign of the threshold B over which the second acceleration waveform is exceeded. On the other hand, the second acceleration waveform is the threshold B. (Or the threshold value -B) or when the threshold value C (or threshold value -C) is reached, the vibration determining unit 1019 determines that the camera is not shaken correctly (NO in S703). In this case, the vibration determining unit 1019 determines whether or not the magnitude of the shaking motion (the magnitude of the detection acceleration) is larger than the predetermined value (the threshold value ± C in FIG. 5) in S710. If the peak value of the second acceleration waveform does not exceed the threshold B (or threshold B), the vibration determining unit 1019 ends the shaking motion detection (S708). The system control unit 1014 validates the operation by the operation unit 1017 (S709). On the other hand, when the peak value of the second acceleration waveform reaches the threshold value C (or the threshold value -C), the vibration determining unit 1019 warns as described above (S711). The processing of the step after S708 is as described above.

At this time, the second acceleration waveform needs to be detected based on a threshold value of a sign different from the threshold value used for the detection of the first acceleration waveform detection. For example, when the first acceleration waveform is detected based on the threshold value -A (the first acceleration waveform in which the peak is concave is detected), the second acceleration waveform is detected based on the threshold value A. There is a need. This is because the first acceleration waveform corresponds to the preparatory operation before the present operation, and the present operation is opposite to the preparatory operation.

In S703, when the vibration determining unit 1019 determines that the camera is shaken correctly, the system control unit 1014 passes the display control unit 1013 to the image display unit 1012 at the time of detecting the end of the second acceleration waveform. The displayed image is changed (S704). The detection time point of the end of the second acceleration waveform is the time point when the second acceleration waveform crosses the threshold A (or threshold value -A) again (time point 313 in FIG. 5). When changing the image to be displayed, the image may be changed in the order of the file name or number, or may be changed in the order of the date and time when the image was taken or the date and time recorded on the recording medium 1010. Depending on the sign of the threshold value used in the detection of the first or second acceleration waveform, the order of changing the image may be reversed in the forward and reverse directions. Nevertheless, when a mode for displaying images in random order is set, such as random reproduction, the displayed image is changed regardless of the sign of the threshold value.

In S705, the vibration determining unit 1019 determines whether the acceleration detected by the vibration detecting sensor 1018 is greater than the threshold value -A and within the range of the threshold value A. While the state in which the detection acceleration is larger than the threshold value -A and in the range below the threshold value A continues, the vibration determination unit 1019 measures the vibration duration time t2 (S706). The vibration determination unit 1019 then determines whether the vibration duration time t2 is equal to or greater than the threshold value E (S707). When the vibration duration time t2 is equal to or greater than the threshold value E, the vibration determining unit 1019 determines that the camera has stopped, and ends the detection of the shaking motion (S708). And the system control part 1014 validates operation by the operation part 1017 (S709).

In this way, after it is determined that the camera has moved, the operation of the camera by the operation unit 1017 becomes invalid when the state of the acceleration (absolute value) does not continue for a predetermined time or less. For example, in the example shown in FIG. 5A, the vibration determining unit 1019 determines that the shaking operation is in progress until a predetermined time E has elapsed from the time point 310 to the time point 314. Therefore, even if the acceleration signal output in the X-axis direction falls within the range of the threshold value ± A, for example, the operation by the operation unit 1017 is invalidated until the state continues for the same time as the threshold value E. FIG.

On the other hand, in S705, when the detection acceleration is less than or equal to the threshold value -A or more than or equal to the threshold value A, the vibration determination unit 1019 initializes the vibration duration time t2 (S712). Returning to S705, the vibration determining unit 1019 again determines whether or not the absolute value of the detection acceleration is within the range of the threshold value A or less.

In addition, when the absolute value of the detection acceleration is less than the threshold value A, but the vibration duration time t2 is less than the threshold value E (No in S707), the vibration determination unit 1019 increases the value of the vibration duration time t2 and the step after S705. Repeat the process.

As described above, in this embodiment, even when the absolute value of the detection acceleration is less than the first threshold value (less than the threshold value A), if this state is not continued for more than the time period of the threshold value E, the detection acceleration is first displayed. It determines that operation | movement from the time point which reached the threshold value A or -A is continued (one shake operation | movement is performed). As a result, it is possible to prevent the third acceleration waveform from being determined to be a new shake operation.

Although the acceleration of detection of the camera according to the present embodiment is equal to or greater than a predetermined value, when the operation is performed in an excessively short or excessively long period or when strongly performed, it is determined that an error is not detected and that the shaking operation is in progress. This detects the waveform more accurately and provides an operation system that is intuitively understandable. In addition, when the stop state does not continue for a predetermined time, the first, second and third acceleration waveforms corresponding to the series of operations from the preparation operation to the present operation are determined by determining that one shaking operation is continued. Can be detected accurately.

As described above, according to the present embodiment, it is possible to provide a camera which can change an image by shaking the camera in a specific direction in the state of displaying an image, such as in the reproduction mode. In addition, even when the user operates the operation unit in the operation of shaking the camera, unintended instructions are not reflected.

In the present embodiment, the shake processing detection process has been described as an example of assigning a change function of the display image to the shake operation in the state where the image is displayed in the reproduction mode. However, the same detection processing can also be performed when assigning a function related to imaging in the imaging mode to the shaking operation. In other words, once it is determined that the camera has moved, the operation by the operation unit is not effective unless the state where the magnitude (absolute value) of the acceleration is smaller than the predetermined value for more than a predetermined time.

In addition, in the first embodiment, when the on of the second switch of the release button 2001 is detected, imaging is performed. In contrast, in the present embodiment, for example, when the release button 2001 is operated in the playback mode, the camera may shift from the playback mode to the imaging mode. At this time, in the regeneration mode, when the on-off of the first switch by the half stroke operation of the release button 2001 is ignored, and when the on-off of the second switch of the release button 2001 is detected, the reproducing mode is selected from the reproducing mode. It may also be carried out. In this case, while the first switch is in the on state, the vibration of any one of the X-axis, the Y-axis, and the Z-axis of the camera is not detected, and when the operation of the camera by the operation unit 1017 becomes effective, The ON of the first switch is also effective.

(Third Embodiment)

Next, a third embodiment of the present invention will be described. Since the configuration of the camera of this embodiment may be the same as that of the first embodiment, description of the configuration is omitted. This embodiment is effective / invalid of the operation device provided on the upper surface of the camera and the operation device provided on the rear side of the operation unit 1017 according to the position of the camera (personal position or landscape position) and the detected vibration direction. It characterized in that to control individually. At this time, the operation device which becomes effective / invalid in this embodiment does not need to be provided in the upper surface or the rear surface of a camera, and may be the operation device provided in the arbitrary surface of the housing of a camera. That is, this embodiment is applicable to the operation device provided in the surface different from any one surface among the operation devices provided in the at least 2 surface of the housing of a camera.

8A and 8B are flowcharts for explaining the outline of the user operation recognition processing in the imaging mode of the camera according to the third embodiment of the present invention.

First, the system control unit 1014 determines the attitude of the camera from the output of the person / landscape position detection sensor 1021 (S9001). Here, in the case of the correct position or the reverse position (the position rotated 180 degrees about the optical axis of the optical system 1001 with respect to the correct position), whether the camera is vibrating in the X-axis direction is determined by the vibration determining unit 1019. (S9002). When it is determined that the camera vibrates in the X-axis direction, the system control unit 1014 invalidates the operation of those provided on the upper surface of the camera among the operation devices included in the operation unit 1017, and those provided on the back of the camera. Operation is valid (S9003). This is because the operation device provided on the upper surface of the camera is likely to be misoperated when the camera is vibrated in the X-axis direction.

Next, the system control unit 1014 determines whether the second switch of the release button 2001 is on (S9004), and if the second switch is on (S9008), performs the imaging operation. When the second switch of the release button 2001 is off, the system control unit 1014 determines whether the operation device on the upper surface of the camera has been operated (S9005). When the operation device of the upper surface of the camera is not operated, the system control unit 1014 returns to the processing of the determination step S9001 of the camera attitude.

On the other hand, when the operation device on the upper surface of the camera is operated, the system control unit 1014 determines whether the second switch of the release button 2001 is on (S9006), and if the second switch is on, performs the imaging operation. (S9008). If the second switch of the release button 2001 is off, the system control unit 1014 determines whether the predetermined time has elapsed since the operation of the operation device on the upper surface of the camera is detected in S9005 (S9007). If the predetermined time has not elapsed, the system control unit 1014 continues the determination step of S9006. When the predetermined time has elapsed, the system control unit 1014 returns to the processing of the camera attitude determining step (S9001).

In S9002, when the determination that the camera is vibrating in the X-axis direction is not obtained, the vibration determining unit 1019 determines whether the camera is vibrating in the Y-axis or Z-axis direction (S9009). If it is determined that the camera does not vibrate in any of the Y-axis or Z-axis directions, the system control unit 1014 validates the operation of all operation devices included in the operation unit 1017 (S9013), and the S9001 Return to processing On the other hand, when it is determined that the camera vibrates in the Y-axis or Z-axis direction, the system control unit 1014 validates the operation of the operation device provided on the upper surface of the camera, and the operation of the operation device provided on the back of the camera is invalid. (S9010). This is done because, when the camera is vibrated in the Y-axis or Z-axis direction, there is a high possibility that an operation device provided on the back of the camera may be misoperated.

Next, the system control unit 1014 determines whether or not the second switch of the release button 2001 is on (S9011), and if the second switch is on (S9008). When the second switch of the release button 2001 is off, the system control unit 1014 determines whether the operation device on the back of the camera has been operated (S9012). If the operation device on the back of the camera has not been operated, the system control unit 1014 returns to the processing of the determination step S9001 of the attitude of the camera.

When the operation device on the back of the camera has been operated, the system control unit 1014 executes the processes after S9006 described above.

In S9001, when the pose of the camera is other than the normal or reverse position, the pose of the camera is at a position where the grip of the camera is above or below (typically 90 degrees or -90 from the normal position about the optical axis of the lens). Position rotated). In this case, the vibration determining unit 1019 determines whether the camera is vibrating in one of the X-, Y-, or Z-axis directions (S9014). If vibration is not detected in any of these axial directions, the system control unit 1014 validates the operation of all operation devices included in the operation unit 1017 (S9013), and returns to the processing of S9001. . On the other hand, when vibration is detected in any of these axial directions, the system control unit 1014 validates the operation of the operation device provided on the top of the camera, and the operation of the operation device provided on the back of the camera is invalid. (S9015). This is done because the operation device provided on the back of the camera is likely to be misoperated if the camera posture is vibrated in either of these directions when the camera grip is above or below the camera grip.

Thereafter, the system control unit 1014 performs the same processing as S9011 and S9012 in S9016 and S9017.

As described above, in this embodiment, the effective / invalidity of the operation of the operation device provided on the top of the camera and the operation of the operation device provided on the back of the camera are individually determined according to the attitude of the camera and the vibration direction of the camera. Run As a result, in addition to the effects of the first embodiment, it is possible to perform careful control to distinguish between an operation device that is likely to be misoperated and an operation device that is unlikely to be misoperated.

At this time, also in the present embodiment, when the vibration in the X-axis, the Y-axis, or the Z-axis direction is detected in S9002 and S9009, as in the first embodiment, the system control unit 1014 measures the vibration beforehand. Recognize as an instruction or command correlated to a direction (or a combination thereof). The system control unit 1014 then performs an operation corresponding to the recognized instruction or command.

(Modified example of the third embodiment)

As a modification of the third embodiment, in the regeneration mode, a combination of the second embodiment and the third embodiment is also available. That is, as in the third embodiment, a method of invalidating the operation of the operation device of the camera in accordance with the posture and the shaking direction can be used. In this case, the time for detecting the shaking motion is determined as the invalid time. That is, if the acceleration signal output is outside the predetermined threshold range (for example, the range of the threshold value ± A or less in Fig. 5A), it is determined that the shaking operation is started, and the state in which the acceleration signal output is within the predetermined threshold range is If it continues for more than a predetermined time (for example, threshold value E of FIG. 5A), it is determined that a shaking motion has stopped. In this case, determination of S701 in FIG. 7 is performed for each axial direction (S9002, S9009 in FIG. 8A, and S9014 in FIG. 8B), and a process of invalidating the operation unit in step S702 in FIG. S9003 and S9010 of 8a and S9015 of FIG. 8B).

(Other Embodiments)

In the above first and third embodiments, the operation (complete stroke of the release button 2001) corresponding to the start command of imaging is not invalidated during the operation of the operation device. However, the operation corresponding to the start instruction of imaging may also be invalidated. In this case, in S8005 of the first embodiment, the operation of all the operating devices is invalidated, and in S9003 of the third embodiment, the operation device provided on the upper surface of the camera including the complete stroke of the release button 2001. The operation is invalid.

Aspects of the present invention may also be implemented by a computer of a system or apparatus (or devices such as a CPU or MPU) that reads and executes a program recorded in a memory device to perform the functions of the embodiment (s) May be realized by a method performed by a computer of the system or apparatus, for example, by reading and executing a program recorded in a memory device to perform the functions of the embodiment (s).
